To explore the value of ultrasound in evaluating the anatomical structures around the master knot of Henry (MKH).
Ultrasound examinations were performed on 200 feet of 100 adult volunteers. The length of each foot was measured, and the distances from the medial border of the MKH to the medial malleolus (MM), the navicular tuberosity (NT), the interphalangeal joint of the hallux (IP), and the medial plantar artery (MPA) were measured. The layered tissues formed by the slipping of the tendon of the flexor hallucis longus (FHL), the quadratus plantae muscle (QP), and the tendon of the flexor digitorum longus (FDL) were determined. The ratios of each length variable to the foot length were calculated, and the relationship between each tendon-related parameter and the foot length was estimated based on regression analysis. The ability of ultrasound to display the relationship with plantar blood vessels, layered tissues, and other aspects was evaluated.
The average foot length was 23.27 ± 1.43 cm. Distances from MKH to MM, NT, IP, and MPA were 7.51 ± 0.75 cm, 1.92 ± 0.23 cm, 13.03 ± 0.69 cm, and 0.18 ± 0.05 cm, respectively. Layered structures: 97% two-layer, 3% three-layer. Foot length strongly correlated with MKH-MM, MKH-NT, and MKH-IP. A regression equation was derived to predict tendon-related parameters, aiding MKH-anatomical landmark relationships.
Ultrasound examination holds significant value in evaluating the anatomical structures of the plantar region.
探讨超声在评估亨利主结（MKH）周围解剖结构中的价值。
对100名成年志愿者的200只脚进行超声检查。测量每只脚的长度，并测量MKH内侧边界至内踝（MM）、舟骨粗隆（NT）、拇趾趾间关节（IP）和足底内侧动脉（MPA）的距离。确定由拇长屈肌腱（FHL）、跖方肌（QP）和趾长屈肌腱（FDL）滑动形成的分层组织。计算每个长度变量与脚长的比值，并基于回归分析估计每个肌腱相关参数与脚长之间的关系。评估超声显示与足底血管、分层组织及其他方面关系的能力。
平均脚长为23.27±1.43厘米。MKH至MM、NT、IP和MPA的距离分别为7.51±0.75厘米、1.92±0.23厘米、13.03±0.69厘米和0.18±0.05厘米。分层结构：97%为两层，3%为三层。脚长与MKH-MM、MKH-NT和MKH-IP密切相关。推导了一个回归方程来预测肌腱相关参数，有助于确定MKH与解剖标志的关系。
超声检查在评估足底区域的解剖结构方面具有重要价值。
